What is a 'ordinary List' to you? I thought (,) constructs a Lazy list?

about the LHS being a list of
scalars (e.g. ($a, $b, $c) = foo()), this post only speaks about
using lists containing @arrays as lvalues).
If we generally recommend this solution especially to newbies, it
has got the additional property that
my ($foo, $bar) := foo
()), this post only speaks about
using lists containing @arrays as lvalues).
BTW, for simplicities sake perhaps there is an MMD on infix:,,
one for lvalue context, the other for read only context?
discarding any additional arguments, i.e. assuming
my ($foo, $bar, [EMAIL PROTECTED

Hi,
I've been wondering how to lazy lists will work.
The answer Correctly, don't worry about it, is entirely acceptable...
The intent of this example in S06 seems clear, make @oddsquares
a lazily filled array of squares of odd @nums:
S06/Pipe operators
It [==] binds the (potentially lazy)
With cons based lists, past stream values are no longer referred to
so can be reclaimed, but we have random access arrays.
That's about where my wondering stopped.
It started again. @primesquares.shift would do it

are essentially
references. This is consistent with other languages where two things are
true at the same time:
1. Arrays and such are passed by reference
1. You don't have to dereference arrays and such before using them
Heh, there's that thread: It's subject was Re: Arrays, lists, referencing
Hi,
I'm lost. I read some Perl 6 related things and think I missed an
important announcement.
What is a list reference?
It is as if lists and arrays are the same thing in Perl 6, but other
documents use the words as they are used in Perl 5.
So I guess my actual questions are:
What is an array
